桥式起重机箱型主梁的模糊优化设计

The Fuzzy Optimization Design of the Main Box Beam in Bridge Crane

运用模糊优化理论，提出了桥式起重机箱型主梁的模糊优化设计方法．按照重量最轻的原则．建立了桥式起重机箱型主梁的模糊优化数学模型，给出了箱型主梁模糊优化的计算实例．

In this paper, according to the principle of fuzzy optimization, the fuzzy optimization design method of the main box beam in bridge crane is introduced. With the minimum weight as objectives, the mathematical model of fuzzy optimization design of the main box beam is established. The Calculation of the example shows that obvious technical and economical benefit will be obtained by this design method.
